FBAR late filing penalty: Guide for Americans and US expats

If you're a US person with foreign bank accounts, you need to be aware of the FBAR late filing penalty. Missing this filing can trigger penalties ranging from zero (if you qualify for certain programs) to thousands of USD per year or even criminal charges in serious cases.

Wondering which FBAR late filing penalty applies to you? The rules largely depend on whether your failure to file was intentional, how many years you missed, and what you do next.

Here is everything you need to know.

What is FBAR & who must file it?

FBAR stands for Foreign Bank Account Report. It's an information form (not a tax return) that tells the US government about your foreign financial accounts.

You must file an FBAR if:

• You're a US citizen, Green Card holder, or resident alien, and
• The total balance of all your foreign accounts combined exceeded 10,000 USD at any point during the calendar year¹

The 10,000 USD threshold applies to the aggregate of all your accounts, not each account individually.

In other words, if you had three accounts with balances of 4,000 USD, 3,500 USD, and 3,000 USD, and they all hit those amounts on the same day, you'd cross the FBAR reporting threshold and need to file.

Foreign accounts include checking and savings accounts, brokerage accounts, mutual funds, and certain other financial assets that you may have outside of the US.

What is the FBAR deadline?

The FBAR deadline is April 15 of the year following the calendar year you're reporting. For example, if you're filing for foreign accounts you held in 2026, the FBAR is due April 15, 2027.¹

If you can't do your FBAR filing on time, you get an extension to October 15. The FBAR extension happens automatically, so if you miss April 15, you still have until mid-October to file without any FBAR penalties.¹

FBAR late filing penalties

There's no single penalty amount for filing your FBAR late.

What you face depends on whether the IRS considers your failure intentional (willful) or unintentional (non-willful). Factors like how many years you missed and whether you come forward before the IRS contacts you also play a major role.

Overall, the FBAR late filing penalties break down into 3 main categories:

Most people who missed filing their FBAR fall into the non-willful category.

If you come forward before the IRS contacts you and use the appropriate correction program, you may face reduced penalties or no penalties at all. In contrast, willful penalties can be very serious.

Non-willful FBAR penalties

A non-willful violation means you didn't file because you didn't know about the requirement or made an honest mistake. For example, maybe:

• You thought the 10,000 USD threshold applied per account and not to all accounts combined
• You opened your foreign account(s) recently and weren't aware of the filing requirement
• You relied on professional advice that turned out to be wrong

For non-willful violations, the maximum penalty is 16,536 USD per FBAR form (adjusted annually for inflation). Following the 2023 Supreme Court decision in Bittner v. United States, this penalty applies per annual report and not per account.¹

That means that if you failed to file FBARs for 4 years and had 10 foreign accounts each year, you'd face a maximum of 4 penalties (1 per year).

Here are a few examples of how it works:

The IRS can also waive the penalty. For example, if you report all the income from your foreign accounts on your tax return and pay any tax due, the IRS often reduces or eliminates the FBAR fine, especially if you come forward voluntarily.

Willful FBAR penalties

A willful violation means you knew about the FBAR requirement but chose not to follow it. The IRS may consider your failure willful if you:

• Had foreign financial accounts and didn't disclose them on purpose
• Took intentional steps to hide your foreign accounts
• Ignored IRS notices about missing FBARs

Willful penalties are serious. The civil penalty is the greater of $165,353 or 50% of the account balance at the time of the violation, and this applies per year.¹

Criminal penalties

Criminal penalties for FBAR violations are rare and usually only apply to cases involving deliberate fraud, tax evasion, or unusually large amounts of money.

But if the IRS refers your case for criminal prosecution, the potential consequences are serious and can include:

Criminal penalties can be imposed on top of civil penalties, meaning you could face both a financial penalty and prison time for the same violation.

That said, if you missed filing your FBAR but reported all your income, paid your taxes, and came forward voluntarily, criminal prosecution is extremely unlikely. The IRS reserves these charges for cases where the evidence shows intentional wrongdoing and a pattern of deception.

In other words, most regular Americans are safe from it.

What is the FBAR statute of limitations?

The IRS has 6 years from the filing due date to impose penalties for FBAR violations.¹

The 6-year clock starts on April 15 of the year following the calendar year you're reporting, even though you have an automatic extension to October 15.

For example, if you should have filed an FBAR for 2021, that filing was due on April 15, 2022. The IRS has until April 15, 2028, to assess penalties for that year.

Once that date passes, the 2021 FBAR is generally outside the statute of limitations.

What to do if you’ve missed the deadline

If you realise that you missed filing your FBAR, there are things you can do to avoid penalties.

The IRS has a few different programs to help you come forward and reduce penalties, but your options narrow down once the IRS contacts you first.

Here's what to do based on your situation:

Situation 1: If you reported all income and paid your taxes, but only missed the FBAR

Use the Delinquent FBAR Submission Procedures.

You need to file your late FBARs electronically through the BSA E-Filing System and mark them as "delinquent." The system will ask you to include a brief statement explaining why the filing is late.

If you included all the income from those accounts on your tax returns and paid what you owed, and the IRS hasn't reached out to you yet, you'll usually face no penalty.

Situation 2: If you missed the FBAR and didn't report foreign income

Use the Streamlined Filing Compliance Procedures.

This program is for non-willful violations where you failed to report foreign income or file required forms. You'll need to file 3 years of amended tax returns, 6 years of FBARs, and a certification form confirming the failure was non-willful.¹

For US residents living abroad, the FBAR penalty is typically 0%. For those living in the US, a 5% miscellaneous offshore penalty may apply based on the highest unreported account balance.¹

Situation 3: If you suspect potential willfulness or criminal exposure

Use the IRS Voluntary Disclosure Practice (VDP).

This program is for taxpayers who may face criminal prosecution. It typically results in civil penalties, but reduces the risk of criminal charges.

Situation 4: If you're not sure

Get professional help before late FBAR filing.

A tax preparer with experience in FBAR compliance can review your facts and guide you toward the best decisions.

---

How serious the FBAR late filing penalty is mostly depends on whether your failure to file was non-willful or willful.

Non-willful violations are often waived with reasonable cause. But if you didn't file an FBAR on purpose, willful violations trigger much harsher penalties and can even lead to criminal charges in serious cases.

If you missed filing your FBAR, the best approach is to come forward using one of the IRS's correction programs:

• Delinquent FBAR Submission Procedures if you only missed the FBAR
• Streamlined Filing Compliance Procedures if you also missed reporting foreign income
• Voluntary Disclosure Practice if willfulness or criminal exposure may be involved

Most Americans will be able to avoid or at least reduce non-willful penalties if you're proactive, but it's important to take action instead of hoping that the US government just won't notice your late FBAR.

If you're living or managing money across different countries, FBAR compliance is just one piece of staying financially organized. Another thing to watch is how much you're paying to move money internationally.

Banks and many money transfer providers often charge hidden fees by marking up the exchange rate when you convert currencies, such as from USD to EUR. Those markups can add up fast, especially if you're sending or converting money regularly.

To move money across borders with more transparency, no markups, and low fees, use Wise.
